Filed: 1978-10-05
Abstract: PURPOSE: To surely produce the sound centrifugal castings by keeping the oxygen density in the atmosphere of a mold and molten steel pouring member at the specific value or under.  
     CONSTITUTION: The oxygen density in the atmosphere in a rotary mold or the rotary mold and molten metal pouring member is reduced to at least 3% or under, preferably 0.3% or under. As a means of this, the atmosphere substitution by inert gas such as nitrogen, argon or other is accomplished. A shutter 7 is provided in the casting side opening where the spout 4 of a mold 1 is inserted, whereby the inside and the atmospheric air is shut off. A piping 9 for feeding inert gas is connected to this device 7. A shutter 6 is disposed to the counter casting side opening of the mold 1 as well and a piping 8 for feeding inert gas is connected thereto. A piping 10 for feeding inert gas is provided in the mold. By these devices, etc., the inert gas is filled over the entire part of the inside of the mold 1, the inside of the spout 4 and the inside of the well part, whereby oxygen density is reduced.

Title: Temperature compensating method for oscillator and oscillator compensated for temperature
Inventor: PEETAA HEIMURIHERU
IPC: H03K17/95
Filed: 1982-07-16
Abstract: A method of using the temperature coefficient of the copper resistance of an oscillating coil to compensate for the temperature coefficient of the quality factor of the same oscillating coil. To this end, a voltage proportional to the copper resistance of the oscillating coil is generated across the oscillating circuit. The oscillator according to the process comprises an oscillating coil which comprises a high frequency litz wire. In order to access the copper resistance of the coil one of the litz wires is separated from the other wire at a first terminal of the coil and separately connected to a second terminal of this coil. From this second terminal, the coil is seen as a bifilar coil. A constant alternating current source is connected to the second terminal in order to generates across the oscillating circuit a voltage proportional to the copper resistance of the coil. The oscillator is preferably used for proximity switches having relatively large switching distance.
